You can use the Index Array primitive function and use the 'index (page)' input to specify which page you want to extract from the 3D array. The example below is by no means efficient because it is not scalable, but it should help illustrate what to do:

Hahaha I'm so stupid!
Never recognized the Wrench Tool Icon.
Knowing its functionality, it's quite easy to manipulate the control. Thank you very much for your help and for the links with former information 🙂

From my understanding, your 3D array (10x240x132) is in face a 10 page 2D array (240x132). The dimensions of the 3D array are row, column, and page. So each page (3rd dimension of your array) includes one second of data in a 2D array (240x132).
Is there a specific way you are wanting to display the frame grayscale data? Do you want to see 10 separate 2D array's, each containing one second worth of data (240x132)?

You can quite get there customizing the control.
this for instance is a q&d expansion of the button (on windows it might actually look better), you can always replace the pulldown button image with anything nicer.

Btw, perhaps the thread belongs to the UI subforum rather.

Hi Folks,
trying to create a GUI that should be used on touch screens in productions. The problem is: Changing the size of the controls will not affect it's special function areas (like the little button for the Drop Down List to show up).
By means of this the gui is entirely not usable with gloves which will cause those poor people that have to use the software to darn me 😞
Is there a chance to create resizeable controls that do not look like Windows 3.11? Or does anyone know a modern looking scaleable control library?
Thank you very much
Nils

Hi Sir,
Good day.
Thanks for your suggestions and advice. I could not open the attachment that you sent to me. It is stated that the file version is later than the current version. I'm using LabVIEW 2017.
Could you please send me again the files. Sorry for the inconvenience caused.
Thank you very much.
Regards,
Priya

hello everybody,
i have a VI, input a video and get its each frame grayscale, but now it is 3D array(10x240x132),
how can i get 10 page 2D array total (240x132), and per second display one array ,total is ten seconds
Many Thanks,
777.avi
array.vi

Hi Priya,
I cannot run one VI as there are missing subVIs in STrace.vi. I have attached a VI where I have combined the 2 block diagrams. This is not an ideal solution. A better way would be to use each VI as a subVI, then place each subVI on a calling VI. To do this you will need to create a connector pane for each of your VIs. There are plenty of online tutorials that explain how to do this.
One last comment. This site is intended for LabVIEW advanced users. You may find more appropriate help on the ni.com web site. There is also a Facebook group (https://www.facebook.com/groups/430271233771850/) that may be helpful.

I'm attempting to get LabVIEW 2018 along with DAQmx and VISA installed on a machine (virtual) running Centos7 and am wondering if anyone else is doing similar.
The main problems I've run into, by following NI's instructions for DAQmx and LabVIEW 2018 support is that it appears some of the DAQmx tools don't install (e.g. "lsdaq") and the additional NI software doesn't appear in the "Applications >> National Instruments" Gnome GUI menu.
I can access serial devices once NI VISA is installed (after adding myself to the "dialout" group), but cannot see or access any DAQmx devices using their method in the link above. I have had some success using previous versions of DAQmx for Linux, but ran into issues and conflicts between modules used VISA and DAQmx.
At any rate... I'm wondering if anyone has gotten something LV2018, VISA and DAQmx to work on Centos7 or RHEL7 yet... and if so, what issues/fixes/workarounds you had to do in order to get it to work.

I have a need to hit several front panel buttons of a sub vi in sequence. The sub VI houses an event structure that must happen in order to make a certain thing happen.
I have a flat sequence structure. that turns off and on local variables that are then fed into the sub VI.
The subVI is called in its own while loop.
the flat sequence is running and the local variables are changing correctly. However, the subVI in the while loop will not execute causing the event structure inside the subVI to not detect a change and nothing happens
The while loop that contains the subvi has no connects in or out of it, its all local variables
Any recommendations on how to fix this? Thanks

So when you run the VC++ example you get an error! Well that is hardly LabVIEW related isn't it?
You must make sure that you pass the right VID (vendor ID) and PIC (product ID) as programmed in the chip. The chips should come with a default VID and PID from FTDI but it can be changed by a utility from FTDI. Check in the Windows device manager for your interface and in the driver settings you can see the VID and PID values, but they are in hexadecimal notation.

I am trying to integrate or combine two different VI in LabVIEW. One of the VI is responsible to measure the airflow through a USB device connected to the computer. The other VI is responsible for sound acquisition through audio jack. Since I’m quite new to this LabVIEW, I tried to copy and paste the sound acquisition block diagram into the other block diagram which measures the airflow. After the insertion of the block diagram of sound acquisition into block diagram of airflow measurement, only the sound acquisition program runs and displays sound signals. But the airflow measurement was not working and even not displaying in the graph. I don’t know how to connect the sound acquisition program with the airflow measurement.
Is it copy pasting the block diagram is possible to integrate the two VI? Is there any other way to combine the two VI?
Here I attached the two different VI, the VI for airflow measurement (STtrace) and the VI for sound acquisition (microphone setup 2_listen).
Could anyone help me to solve this problem?
Thanks.
Regards,
Priya

As of the latest Tools Network version, the palettes should also appear in the "Flatten/Unflatten String>>JSONtext" palette, in place of the install link in LabVIEW 2019. It's programmatically added, so let me know if that doesn't work for you.

Hi,
Say, I am going to build a system and control it using labview through DAQ.
For example, the system has stepper motors to move a heating chamber back and forth, a temperature monitoring system, a pressure controlling gauge etc.
Now, before diving into building the actual system, Is it possible to make a simulation of the whole device and integrate the necessary LV coding, where I can show on screen how the LV program controls the different parts of the system?
